Which two campus network problems indicate a need for QoS? (Choose two.)

Excess jitter and bandwidth-related packet loss are direct indicators that Quality of Service (QoS) is needed. Jitter, the variation in delay for packets, severely impacts real-time applications like voice and video, making conversations unintelligible. QoS mechanisms can prioritize these time-sensitive packets to minimize jitter. Bandwidth-related packet loss occurs when network congestion causes routers to drop packets due to insufficient capacity. QoS can prioritize critical traffic, ensuring it gets the necessary bandwidth and reducing loss for essential applications. Port flapping is a physical layer issue, not directly addressed by QoS. Misrouted packets indicate a routing protocol or configuration problem. Duplicate IP addresses are a network addressing issue.
